Common sense is why he’s President Trump. This is a no-brainer, and the kind of thing you can’t poll, because everyone wants to think they are tolerant and progressive socially. But it makes absolutely no sense, at a minimum, to enlist additional recruits whose main commitment in life is to be a different gender than what their chromosomes indicate. My guess is that the majority of thinking people found the “Don’t Ask, Don’t Tell” policy good enough, and it should have been kept that way.
